Quick Verdict — 8.5/10

Full Specifications

Design & HD Animation Screen

The MO20000 Pro is the most compact device in the current Lost Mary lineup. At 94.4mm × 31mm × 24mm, it's noticeably smaller than the MT35000 and significantly more pocketable than the NERA 70K. The body uses splash-pattern or marbled designs that vary by flavor — visually distinctive and more eye-catching than the understated finishes on the Ultrasonic and NERA.

The star feature is the Mega HD Animation Screen — and "mega" isn't exaggeration. It's the largest display on any Lost Mary device and arguably the most impressive screen on any disposable vape. It shows real-time battery percentage, e-liquid level, current wattage setting, and a puff timer that tracks your session duration. During vaping, animated graphics flow across the screen, adding visual flair without being distracting. Unlike the MT35000's blend-in display that hides when inactive, the MO20000 Pro's screen is always accessible with a button press.

Build quality is good for the price, though the all-plastic construction feels less refined than the NERA 70K's magnetic pod system or the Ultrasonic 35K's satin-finish body. The rounded edges and slim profile make it comfortable for extended hand-holding, and the single control button on the front is well-placed for thumb access.

Adjustable Wattage — 13W to 25W Deep Dive

The MO20000 Pro is the only Lost Mary device with true wattage adjustment. Other Lost Mary devices offer binary mode switches (Normal/Turbo, Smooth/Turbo); the MO20000 Pro gives you a full 13W–25W range adjustable in 1W increments via the front button. The current wattage displays on the HD screen in real time.

This level of control fundamentally changes how each flavor performs. Dragon Drink at 16W is a light, refreshing tropical sip; at 24W it becomes a rich, syrupy mango punch. Miami Mint at 14W is a gentle, cool breeze; at 22W it's an intense, icy blast that fills the mouth. No other Lost Mary disposable gives you this range of experience from a single flavor.

The practical impact on puff count is real, though. At 13–16W, you'll approach the advertised 20,000 puffs. At 20–25W, expect 12,000–15,000. The device doesn't warn you when high wattage is burning through e-liquid faster — you just need to watch the e-liquid indicator on the screen.

3-Level Adjustable Airflow

A slider on the bottom of the device controls three airflow positions: tight, medium, and open. Combined with wattage adjustment, this gives you a broader experience range than any other Lost Mary device.

Tight airflow + low wattage (13–16W) produces a firm MTL draw that's closest to a traditional cigarette — satisfying for 5% nicotine salt and very discreet vapor. Medium airflow + mid wattage (17–20W) is the balanced sweet spot for most users. Open airflow + high wattage (21–25W) creates a restricted DTL (direct-to-lung) draw with visible clouds — the closest any Lost Mary gets to a sub-ohm experience.

In practice, we found the tight and medium positions to be the most useful for daily vaping. The open position at high wattage is fun for short sessions but drains the battery and e-liquid quickly.

Real-World Performance

The 0.9Ω dual mesh coil handles the full 13–25W range well, with consistent flavor and no burnt taste from first puff to last — even during extended sessions at higher wattages. The mesh design heats evenly, which means flavor is stable across the coil's life. This is especially important for a device that lets you push wattage to 25W, where uneven heating would produce hot spots and dry hits.

Draw activation is responsive at all wattage levels. There's no perceptible delay between inhaling and vapor production, which is critical when you're using the device at higher wattages where delayed firing would cause inconsistent hits.

The puff timer is a feature that no other Lost Mary offers. It displays how long your current draw lasts and tracks cumulative session time. For users who are mindful of their nicotine intake, it's a genuinely useful tool. It doesn't nag you or set limits — it just informs.

At the sweet spot (17–20W, medium airflow), the MO20000 Pro delivers a warm, flavorful draw with moderate vapor density. It's less smooth than the Ultrasonic 35K's ultrasonic mist and less consistent than the MT35000's Smooth Mode — but it offers more control than either. The trade-off is appropriate for the price point.

Flavor Review — All 19+ Across 3 Editions

The MO20000 Pro offers the widest flavor selection in the Lost Mary lineup — 19+ options across Standard, Super, and Space Limited editions. Unlike the MT35000's "+" enhanced formulas, these are standard formulations. The advantage is variety; the disadvantage is that individual flavors aren't as bold as their "+" counterparts on the MT35000.

Standard Edition (15 Flavors)

Dragon Drink is the MO20000 Pro's signature flavor and the reason this device earned its place in our top rankings. Sweet dragon fruit meets tropical mango in a combination that's exotic, refreshing, and endlessly replayable. Wattage control is essential here: at 16–18W it's a light, juicy tropical drink; at 22–24W the mango becomes rich and syrupy. No other Lost Mary device lets you shape this flavor so dramatically. It's our #6 overall on the Best Lost Mary Flavors Ranked list.

Blue Baja Splash is a Space Edition standout — lime and blueberry with a fizzy, soda-inspired edge that's bold and unique. It doesn't taste like any other Lost Mary flavor and benefits from mid-high wattage (20–22W) where the fizzy character really pops.

Blue Razz Ice and Miami Mint are proven performers that taste great on the MO20000 Pro, though they don't reach the heights of their versions on the Ultrasonic 35K or NERA 70K respectively. The standard formulation is good, but the lack of "+" enhancement or ultrasonic delivery means they're slightly less complex.

Super Edition (4 Flavors)

Grape Jelly is the Super Edition's best addition — a sweet, authentic Concord grape with a smooth jelly finish. At higher wattage (20–22W), the sweetness deepens into a dessert-like richness. Sour Strawberry Dragon adds an interesting sour-sweet tension with dragon fruit tartness.

Space Limited Edition (5 Flavors)

Pear Drop is a pleasant surprise — a nostalgic British-inspired pear candy that's sweet and slightly tangy. Pina Colada adds coconut-pineapple tropical warmth.

Battery Life & Charging

The 800mAh battery delivers approximately 1–1.5 days of moderate use at the 17–20W sweet spot. At lower wattages (13–16W), you can stretch it to nearly 2 days. At max wattage (25W), expect to charge daily. USB-C charging takes about 45–60 minutes for a full charge.

The HD screen shows exact battery percentage during use and charging — a significant advantage over the Ultrasonic 35K's basic LED indicators. The screen also shows wattage in real time as you adjust, making it easy to fine-tune your settings.
